Enter the data from this table into SPSS. Remember to enter data in the Data View window. Also, recall that SPSS treats each row as if it is one participant. In order to show SPSS that this is a between-subjects design, you will need to format these data into two columns. One column will show which condition the participant was in. The second column will contain the participant's data (how many days it took to recover from jet lag).

A one-way ANOVA of these data. In the menu, go to "Analyze", "Compare Means", then "One-Way ANOVA". Once you are there, put your independent variable/study conditions in the Factor box. After that, put your dependent variable in the box labeled "Dependent List".

• Check the box for Estimate effect size.
• Select Post Hoc and select the Scheffe test and hit Continue.
• Select Options and select Descriptive and Homogeneity of Variance Test then hit Continue.

Finally, select OK. You are ready to run the test!

Answer the following questions based on your SPSS output.

3. Based on the SPSS output, do these data violate the assumption of homogeneity of variance? Explain where you looked in the output to answer this question. (1 point)

4. Is there a statistically significant main effect found in this ANOVA? Explain where you looked in the output to answer this question. (1.5 points)

5. Using the data in the ANOVA table, calculate eta squared. In addition to calculating this value, compare it to the results you see in the ANOVA Effect Sizes table. Does your eta squared value match any values in the table? (1.5 points)

6. Describe what the post hoc analysis in the SPSS output reveals about the results of this study (e.g., what conditions are significantly different from one another). (1 point)
